Finding Feature Information

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see
Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to

Prerequisites for Configuring Capabilities Manager

To ensure that a router has Capabilities Manager available, enter the
showservice-routingplugincapman command.
To enable a router to distribute its capabilities information, configure a SAF Forwarder on the router.

To view capabilities information present on other routers in the network, configure a SAF Forwarder.

Information About Capabilities Manager

Capabilities Manager is enabled by default at system startup. At startup, it registers as a Service Routing Client and proceeds to discover various capabilities of the hardware and software platform.

Capabilities Discovery

Capabilities Manager only discovers whether a capability is supported on the local system. It does not discover whether the capability is configured or enabled or discover any other information about the capability for other routers in the network.

Capabilities information will be installed into the local Network Information Base (NIB) as service routing data and made available for advertisement by any SAF Forwarder to the Service Routing network. Capabilities information is passed to the Service Routing infrastructure in XML format and stored in the local NIB.

Interoperability with SAF Forwarder

Capabilities Manager does not advertise capabilities information to the Service Routing network. A SAF Forwarder performs the functions to distribute capabilities information. However, a SAF Forwarder is not required for Capabilities Manager to function. If a SAF Forwarder is not configured, the capabilities information is bound to the local router and is not distributed to other routers in the network. When a SAF Forwarder is configured, it will distribute all capabilities information by default.

Capabilities Information

Capabilities information is installed in the Network Information Base (NIB) as service routing data. It is identified by a SAF address in the form of:

service ID—Capabilities Manager uses service ID 100.

subservice ID—Capability group ID. The subservice ID indicates the group ID of the capabilities data type.

Instance number—Unique identifier for the local router. It is assigned in order of the hardware serial number, default MAC address, IPv4 router ID, or IPv6 router ID.

Capabilities Groups

Capabilities Manager classifies capabilities by group to facilitate query and retrieval, and assigns each group a unique ID. Capabilities Manager provides the following capability groups:

Hardware Group Information

Hardware information is designated as group ID 1. Group 1 provides the following capabilities information, when available. All hardware information may not be available on each platform that supports Capabilities Manager.

Host Name

Platform

Main Memory Size

IO Memory Size

Software Group Information

Software information is designated as group ID 2. Group 2 provides the following capabilities information, when available. All software information may not be available on each platform that supports Capabilities Manager.

XML Schema for Capabilities Data

If you have an Extensible Messaging Client Protocol (XMCP) client (external client) connected to a SAF Forwarder, you can subscribe to the Capabilities Manager, which is service ID 100. The data can be interpreted using the following XML schema:
